TO'ALL WHOM IT MAY OONCERN:

l l Be it known that I, I sAAc Mmmm Susann, of Yonkers, in the.' countyof Westchester, and State of New York, lmvcjuvented certain new 'anduseful improvements in Sewing Machines; and that'thc following isa`full,. c lear, and oxnet-descripntionof the same, reference beinfg hadto the accompanying drawing, injvhichf- Figure 1 represents n. s ideelevation of a sewing mnohino,l embodying my improvements.

.Figgrercpresents on elevation of one end of the same withportionsremcvedto show. the members beneath the table plate of themachine. A

Figure 3 represents a plan of the machine turned upsidedown, so ns toshow the members of .the machine.-

Fgnrcs to' 8, inclusive, represent side views of the needle, shuttle andits appurtenzinc, in different positions. Figures 9 to 15,-inclusive,represent various view s of the shuttle and bobbin or spool end Figure16 represents a' plan of a'portion oi' the needle-arm enditsappurtennnees: l' My improvements hiive reference to the sewingmechanism, thread-,c ntrolling, nndtenson mechanisms, and. feedingmoehainism of sewing mschines,and although I believe the best resultwill be cittained, wheniall my improvements cre combined together in theenmc machine, some of them may be used separately fromthe otherswherever such-separate use may be' expedient. The object of l the-firstimprovement .or pnrt oi' my invention is .to prevent lthe formation ofslack shuttlefthrewd between the guide eye of the shuttle from whichthevthrewd is delivered and the n'crlc upon the table plete ;'t his partof my invention .consists of the'oombinution ct areeip 'routingneedle-her lor carrier, with en oscillating shnttlchaving .itsdelivery'eye'ecineident or thereabouts with its centre of oscillation,so that' the length of shuttle-thread extending-from the eye tothe scam'is substantially. ."the same in evcryposition`1liiloh the shuttleoccupies in its -oscillation. The object' of the second part of theinvention is'to prevent the .shnttlefthrend extending from the seam tothe' shuttle from being splitby 'thelneedlc point in its descent, andfromlie'ing in the yay ofthe shuttle-point iu its movement. This part ofmy inven. tion consists of the. combination' of ven oscillatingshnttlewith a delivery eye arranged et one side of 'the plane: of oscillationof .the shuttle point, sothat the Ashuttle-tln-end extending from theseam tothe shuttle divergoe'- laterally from the truck'v of the needlepoint and the plne of oscillstionlof theshuttle p cnt, andis-out ofeheway of hoth these instruments, vThe object ofthe 'third part of theinvention -is to enable the shuttle to he held laterally in its place inthe machine by a'spring of sutiicient 'rigidity to prevent its escupeendst thc 'samo'tin'i'e to .permit the shuttlet'c move loosely during Athegreat-creport of its movement, so-that thel loop ot' needle-threadmay-pass freely over it. This part of my invention eonsistscf thecombination; of 1 the shuttle with a spring-holder et one side of it,and with vii. stop which prevents. tho spring-holder from bearingagainst .the side of theshuttle-when it is in its proper position-in themachine. Theo l ject ot`.the A fourth part of the 'invention is tomaintain the `shuttle point, atA the time it is'passing by the needlefor the purpose of entering the loop of needlcthread, always in the sameposition, sc esto insure thc seizure of the loop of needle-thread by'the shuttle', while at other times the shuttle is held loosely. Thispart. of tho inventionconsists of the combination of the hloeltor theequivalent instrument which holds the shuttle in place' upon one side,with, a shuttle guide so arrenged atfthe opposite side et4 the shuttle;that it 'guides the shuttle n only when its point is in the vicinity ofthe needle, leaving it free during the remeiuder of its movement. Theobject of the fifth pnrtl of the invention is to facilitate the iovementof an oscillating shuttle by a'reeiprocntingA instrnme'ntf and'itecnsistsof `the combination lof oscillating shuttle drivers with nreciprocating connectingrod, and a spriii g acting c rossvvise to saidrod, s' thttt the shuttle drivers and shuttle are moved from theextremities of their ranges of motion towards thc centros thereof! bye-force which is made up of the force exerted hy' the eennccting rod inthedirectionof its length and thc force' exerted orosswise 'te thatdirection by the spring. TheA sixth part of my invention has reference.to the taking: up of theelaclr needle thread loft after the passage ofthe shuttle through the l'oep presented to it' hy' thc oe'dle',- and itsobject is to insure thetightening of the stitch. This part of myinvention consists of thelcomhination of 'the needle-holder andreciprocating shuttle with a vibrating take-up lever (or its equivhlent)operated hy a cam, (or its equivalent) and a spring, in such mannerthatthe tak elup lever yields up slack during the entrance of the loop ofneedle-'thread by the shuttle, but resists the complete extension of theloop 'of needle-thread by the shuttle, and thoreby'enubles the latter todraw the last stitch of needle-thread tight to the materiah The objectof the seventh part of the invention is toideliver the'thread te thethread-tension apparutus, .or thread tension as it is commonly called,without strain upon it, whatever be thevarying resistance which thesppohof Aneedle'rthroad oll'ei's to uuwinding. This part of my inventionconsists of the combination of the standard or other support for thespool, and the thread tension, with n thread-sinkening mechanismarranged between the spool support and the thread tensin, nnd'operatingto withdraw thethreud freni the spool and deliver it.in a slack loop tothe thread tension. The object of thc eighth part of .the inven tion isto enable both the direction in whioli the-.feeding instrument operatesto be reversed, and the extent of its, movement in either direction tehe varied, by thc.,ohauge of posture of the same instrument. This partof my invention consists of the combination of the feeding instrumentand a bar reciprocating erosswise to the movement'thereof, with aturning regulating plete having its slot'extended across the centre onwhich it turns,

- in such manner that -both the direction in whichthe.' feedinginstrument operates, und its extent of mgtion may be .vai'ied bychanging the posture .of the said regulating plato byturni'ng it on itscentre. The objotof the ninth part of the invention is to enable theoperator to regulate the length of `thc feed when lreversing its direc.-

Ation without examination bythe eye; andit consists of the combinationof the revorsingand regulating lover,

or its equivalent, that controls the feed mechanism, with two'adjustable stops which limit itsmovcnient'lin opposite directions, sothatthe feed 'may be reversed andthe citent of -feed determined bymo'ving'theregulating and reversing lever from one stop tos-the other.

1' `rThe sewingmachi'ne which I liavorepresented in the accompanyingdrawings as an' exemplication of a" convenient mode of embodying myimprovements, is likein its general arrangement many maehinenow in use;

it-lias u horizontal' table pl'ute, A', 'to support th'emiitersl t'chescived; a vertical reciprocating ncedle-bar, H,

to carry an eye pointed needle, to thrust it downwards through thematerial and to withdrawit therjfrom, and I it is provided beneath'thctable plate with a shuttle, 'to interlo'op a'sooou'd threadwiththe'thread thx-het through the work by the needle; The needle-harorcarrier, H,` is supported in guides' at thefcndz, of uiieedldoirni, C,which is mounted upon the bed plate, A, of the macliiulej und thisneedle-basis 'driven a revolving crank wrist, a, which projects from theface of a disk, G, scoured to' a' revolving shaft, D,cind works intliegroovc of a transverse cam, secured to the vneedlelmr ;A so thattherevolution ci' the'shaft, D, causes the4 needle-arm to rise and descendin alternate succession, thereby thrusting the needle downward throughan opening or throat* formed in thc table plate of the machine for itspassage and. raising it therefrom. c The shuttle, Z, is 'thin and broad,and is supported edgowise in the machine;.it'has a curved point', a,.toenter tho 'loopofneedle-thread; and is provided with a iiat spool orbobbin, g, igs. 14 and 15, upon which the shuttle thread is wound. Theshuttle, when the machine is at rest, is supported bytwp drivers, f undj', (shownin dotted lines in figs. 5, 6, 7, and 8,)

which project from the faceroffa disk or hub, B-ftlat is secured to ashaft, D'. A This shaft is causodto rodk by connecting it by means ofaconnecting-rod, 0', with a slide, E', to which areciprocating movementis imparted a from the wrist of a crank, S, (secured to an uprightshaft, J,) by means of a connecting-rod, F'. The upright -shaft, J, isconuectedwitlnthe needlshaft,.D; by means of mitre wheels, -(zi GJ, sothat the needle und shuttle are caused to workin harmony; 'andthemotions are so timed that the needle rises slightly before the point ofthe shuttle is cansedtc pass its lineof motion, so that thcneedle-thread is. caused to spread laterally from. the noodle for theentrance of thopoint of the shuttle as .is customary'inshuttle'mschines. Theshuttleis so brc'ad that its lower edgeicxtendsdownwards tothe axis of tho rock-shaft, D', or thoreabouts; hence whenthe shaft, D', cf the shuttle drivers rocks, the shuttle is caused to'oscillater andthe asis upon which it o'soillates, (which isthe axialliuc of the roch-shaft, D,) is at or near its lower edge.4 The shuttleis provided with a delivery eye, l, for the passage of theshuttle-thread from it, at cr near this centre of oscillation, so thatthe lengthpf 'shuttle .thread extending from. this eye to theworlr lying'upon the table plato aboveis substantially always of the sume length,lwhatever be the position in which the shuttle vis pluo'ed by itsdrivers; 'consequently there is'. practically no slack`of shuttle-threadformed by its reciprooatingmovement. The shuttle is guided vertically inits oscillation by a shuttlc-racc, Y, consisting of a curb projectingfrom a block.- Ii', which is arranged cppo` site to tho face of thedisk, of the shuttle drivers, and maintains the shuttle erect 'upon oneside, audin practice the movement of thev shuttle is so rapid, and theradius vof the curb is so small, that asnfiicient amount of centrifugalforce is generated to cause the upper edge of the shuttle to bearagainst the curb, thereby h oep'ing its front aud-rear alternately outof contact with that cnc of the drivers which precedes it in itsmovement, and leaving a narrow space between that driver und theshuttle, open for the passage of the loop of needle- .thi-cad. 'lhcdelivery eye, s, by which the shuttle-thread passes fromthe shuttle, isurranged'at oneside of the plane in which the point of the shuttlemoves, so that the thread extends from the scam formed upon the tableplate above tc the shuttle eye in u line which diverges' vboth from theAplane of movement of the shuttle point und from the line of movement ofthe needle point; hence -the thread is not within the range of motionofeither the shuttle point er the ncedlepoint, and consequently does 'notinterfere with the former and is not liable to be s'plitby the latter.The delivery ey'e may be at either s ide ofth9 shuttle point, but Iprefer to arrange it at the side thereof, which is furthest from thedisk, Il', from which the shuttle drivers project. The requisite tensionupon thc shuttle thread is obtained by passing it through ono ormore ofu series of holes., g, formed in thc shuttle 'casehcfore it is passedthrough the guide hole, s, by-which `it leaves the shuttle. The shuttleis hc'ld odgewise in its place during the greater part of its movementby mcans cfa spring, h, which is secured to tho-disk, B','of lthcshuttle drivers and oscillates with them, but the'range of'motiou ofthis spring holder 4 towards the adjacent sido of the shuttle is limitedby a stop, i, secured tothe driver disk, B', so that-the acting face ofthe spring holder is not permitted tc approach the face of tho block,H', at' the opposite sido of thc shuttle, nearer thun'a distancepredetermined bv the maritim. c n... .mi ---1 A 1 ii a little greaterthantho thickness oi theshutt'ie added `to twice-.thc thicknessiof theooarses't noodlethread which the machineis 'adaptedto use; hence the-shuttleisleft loose in its place during the greater partof itsmovement, nnd'neitherthe spring-holder, h, on ono side, nor the block,H', upon the other, Aoii'ers en impediment 4:t'o the free passage of theloop' of needle-thread. When, however, the shuttle tends-to escapolaterally from' its proper Aposition by bearing the spring-holder, 14,outward irour'the stop, sueheeeapc is resisted by tho full force oiAthat-spring-.holder It is desirable-,that the :shuttlepoihtrshouldalways occupy precisely the saine posit-ion atsthetimeitspontis enteringtbe loop of thread carried by th'e needle in order thatitv nay -enter this loop with eerta'inty.. Thisresult is attained'byfmeans of a'shuttlo `gnide,j, which A'projects upwards at one side' ofi the 'track'.of theshuttlein a position to bear against one of itssides-und press the opposite side of' the shuttle closely againstthefaoeof the block,- H,-for: a short period while the shuttle point is.passing the needle 4und entering tho loop -of necdlefthread; as however,the shuttle guidofis arranged to act vuponthe butt of the s shuttle.while it is inl-tho vionity'ofits mostbackward"position,the*shuttle isin contact with it for but every Y; small fraction of'tslrnovotnent,while during the remdindereof its movement it is loosely -held by thespring:

- holder,1, consequently'the requisite precision of movement is obtainedto insure theentering of the loop of needlethread, while atothertiniesthe. friction of the shuttle against the parts of tho machinewhich-hold it in piace is but slight. The shuttle is caused to bsoillteadstancooif aboutl a third vof4 a. revolution,svhieh'requires theconeetingfrodC andthe pin n of the drivel-disk, while at the.extrernepoint's of their strokes, to approach the straight line drawnthrough the pin' 'n' of the slide E "and the'sxis df' the driver"ro'clr-s'h'aft;V In order to 'ensure the en aocth working of .the-polrts, notwithstanding this. proximity,'a spring m is so applied totheslide E',

The ii'xed i end of the spring l is fornied'nto. nxreye, und issecured by a screw p hence tho position of. the spring maybeadjusted,.(by slacking and retightening the screw,) to calice it to.exert more or less force upon then'eodleithread when the shuttle iserten'ding the loop tg its utmost limit, thereby adapting the strain tothgreater or less iin'encss of the `neodle-thread. The needle-thread issupplied frein a spool Il, supported upon a standard I' secured to theneedle-arm, end s drawn from this spooLby' a. positive mechanism which Itet-'m' a. thread-slackencr,so .thatvit is delivered tothe"threadtension 'under 'the Ysame strnnl at all times, notwithstanding the'dii'forence in tlievdiameters of the mass of 'thread on the spoolatdiierent times.l -The thread-slackenor. ih the present gs'se consistsof a projection K, .scoured to ,the drivingshaftD of the needle-bnr,andthe thread from the .spool is passed through en eyot. above theshaft, thence -around the shaft and theprojeotion, und is then returnedupwards throughnu eye t', above the shaft, so that the thread surroundsthe projection in o loop. The

thread from the last oye, t', is conducted through a spring, nippcrs L,and is' then applied to the thread tension M. The spring .nippers Lconsists of sm'ovable jaw u, pressed by spring o towards a -iixed jawu', so' as to oder a greater resistance to the drawing of the threadbackwards towards the spool' 'than'the spool oiic'rs to the -.pulling ofthread fro'mit' by reason of its friction upon the base en which'itrests and upon 'the standard I. -Tiie drawing of thelthread into theseam by. sewing, lessons the size of the loep surrounding' the shaft Dand its projmtion-K,= and the depression of this projectionby the4turning of the'shaft D tends to expand the loop, and,

as the thread is prevented {rendi-swing baekwdrds from the. nippers, thequantityrequirod to ineke the loop.

large enough to permit the projection K to t,lirn .in-t is'drllwn fromthe spool. The projection K s-so arranged i relatively to the needlecrank-wrist n, that it'drawe the-'thread .from thespool'in theiutervsls-bctweenftho-- periods when the'needlodraws Athrewdf'r'om thetension.. .The revolving projection. K thus slackens the thread,

so that-ithongs in o. loopland-p'asses to the tension without materialstrain upon it, whatever ho the resistance NAN of the .spool tounwiuding. In order that the thread entering the nippers may uotescapethem, I find it expe# dient to'pass it iirst over a soft surface, suchas a piece of cloth', @applied to theAneedle-arrn, andthon partly arounda pin a. i I also groove. theedges of thes tationaryvfnipper-jaw u', ateach sideof the-place ivhere thc movable jaw nips 4the thread.A vIt willbe perceived that the thread-slachcncr above ,described does not.measure out a preciso length of thread'at.eaeh movement, but,simplypnlls it suddenly from the. spool v; "and as the latterl may turn(by reason .of the-sudden pull)'a distanoesu'ihcient to deliver threadenough to form several stitches,

thethrccdslackener does riotnecessarily operatezupon the' thread at eachstitch, but only when' the"lbop of needle-thread thathangs loose betweenthe spool and the thread tension becomes too small to permit the'movement of the slacken'er. The material to be sewed 'is moved forwardat intervals by means of a toothed feed-bar P', vvhose'head moves in anopen'ing .in the 'tableplate of the machine, and is 'moved upwardagainst -the u ndcrside of the material, when it is to be fed by meansof a cam e, projecting from the rim of the disk B' of tbeshuttle-drivers; when the feeding is completed, this cam z permits the-toothed bead of 'the feed-bar to descend in the opening of Athetable-plate. The feed-bar is 'caused toA move horiz'ontally by means of.the lateral movement ofA a b'er Q to, which a reciprocating movementiinthe-'direction of its length is imparted by connecting it With'a leverR,'moved in one direction by a csim secured -totbe upright shaft J, (asrepresented n dotted lines Iin 'g. 8',) 'and in the opposite direction4by a spring b', which bears against the loverand operatesantagonistically .toith'eeam n The lateral lmovement o'f thereciprocating bar'is`eii`ected by causinga pin'. projecting. from itsupper side, a'nd'rcprosentcd in'dotted lines at a', iig. 3,-.to move inan linclined slot formed 'in a plate U; 'and the-recip'- rocatng bar Qisconnected with the i`eedba\- P' by means -o'i a longitudinal slot d inthe former, embracing a pin projecting-from tho latter. It is a greatadvantage in a. sowing machine to beable tov change the direction iniv'hioh the feed moves 'the material, so that the scam may be reversedupon itself, orthat sewing mayL be done in opposite directions, withoutthe necessity of. turningj the work` around the 'needlo.. I t is alsoessential that' the feed mechanism' should be readily adjustable; so asto vary the length of the -stiltchesf'MIn order that such reversal andvariation maybe eected in thcmachin-'c I am' describing, the plate Uhasl jthe form ci' a disk, andis arranged to turn upon its centre, inthe soclr'e't in which it is set;4 p and'its -s lot, as repro-- sentedin dottedv lin'es in fig. 8, extendsdiametrically across the centre onwhichit turns, so that'it is at both.v sides of that contre.

'ofthe `feed-bar) also'orgtends in, the direction of its le'gth, themovement oi` the reciprocating-bar Q, its cam, then imparts lioj'in"mcnt 'to the feed-bar 1".'A When, however', the plate U`is turned thelever W, so that the slot is inclined to theA length of tbcreciprocating-bar Q, inthe direction represented in black dotted linesin iig.' 3, the

iove'inoutof therociprocatingb "by the cam, will'cause its p in,`vvhilemoving in the slot 'of theplate U, to

to the 'cloth in that dircctiomwhch is the reverse of the previousdirection. The plate U is arranged, in the l present case,to turn ineither direction until its slot makes an angle of about 46.* with thedirection of the lcngthof tho reciprocating-bar Q, and the cam is ofsuilicient sise to impart the greatest required 'movementtoIthe'feed-bar,

when the plate is turncd'to those extreme positions; t'vhen-thc plate isturned to some ixitermcdiatepcsition between its vtwo extremes, the feedwill be less, and thc direction ,of fthe feed vill be in one direction,or the reverse,- accerding' as thercgulatng lever W is set to one orother side of its central position. Hence, the'plate U is a regulatingplato, for regulstingboth the direction and extent of the feed, and themechanism above described permits thc direction of the'feed to bereversed, and its extentto be regu-lated, bythe movement of oneinstrument, (the regulating-plata) by the application of the hand of theoperator to 'the regulating and reversing lever, W, 'which controls thcfeed mechanism; this lever' may be secured directly to the 'regulatingplate U, although this' is not expedient, as it would then b'e coveredby the material. When the'feed is reversed, it is frcciuentiydcsirablcthat the operator shculd'bo abicto set the feed mechanism so as'4 to'feedthefmaterial exactly at the same rato in the reversed directionas itwas fed before reversing. In order that this may-be eii'ccted withoutthcnecessity' of Vexamining the machine at the time of reversal,.two stops,N', are applied't'o a gauge-bar M', which is sccurcd'transvcrselybeneath the regulating and reversing lever W, so as tolimit the movementof'that lever 4in either direction.n The stops are secured to thegau'gebar independently of each other,by means oi' screws h',

whose stems pass through slots in the stops, so that the'stcps maybeset;A at any required distance'ifrom the central position of the leverW, when thescrevrs are slacked, andmay be .secured by screwing up5thescrews. When tho stops are thus set, at. oqualdistanees on oppositesides of the-central position of th'o lever W, the extent of feedwill beequal opposite directions, when the lever is moved alternately incontact ivith cach stop. As, however, the stops arc independent of `eachother, they may be set at` different distancesfrcm the central positionof the lever W, and' then the extent of feed will bc different inopposite directions, when the lever is alternately brought in contactwith thc stops, The operator thus -has it in his powcr,.by setting thcstops, 'to' determine the ratc of feed in cach direction and when th'estops have ghecnset for a. particular .lot of work, the operator neednot examine the lever W when hc reverses thc feed, as the stops forroabetter guido for its position than thc eye. l
